C5x7 3rd time steering leaking

[aerodynamica]

Not sure matt, after what Stu said, I thought the rack sent was the wrong type but I measured the throw at 180mm so maybw it is right after all

[PATaMAT]

Hopefully there's not something I've missed because I've gone ahead and got medieval on the housing.

The block chopped off, 25mm hole now 30mm, a bit of a groove to the outside to help a rubber gaiter stay attached, a circlip groove cut in the new 30mm bore for a circlip that I don't have yet..

Pic shows it now and the metal ring now fitted back in.

this is wild
i wonder if it will work for you

[PATaMAT]

the bronze ring is the bearing
From the inside of the housing, the Simering is pressed in,
then the ring is pressed in - the bearing
everything is pressed with a tool to the required depth

if you leave out the bearing ring, it will be bad.

the shaft is inserted into the housing and it's done

Should be able to fit the seals this way and then a circlip.

Are the seals double lipped? If not they seem to be the wrong way round. The lip/spring side should be on the oily side. I realise they're not fitted yet and may just be placed for a photo but after the great work that you're doing it would be a bugger to say the least.

I think this seal is intended as a cover sleeve
The oil seal is under this

Graeme,

You have done a lot of work since my last post, well done. On my last rack I removed the lump and fitted a suspension rubber over the pinion.

I'll be interested in the final result. I've always thought about having a new pinion shaft turned out of good steel, but never costed it up.

I'm glad you're saying that because I actually was going to put them in this way. The one that came out was that way and the ones I saw elsewhere were also that way round.
Incidentally the refurb rack only had 1 seal fitted and the top seal was missing. This had allowed the seal to drift upwards.
I think I'll turn the seal to the orientation you suggest

Hi Kenny, it also crossed my mind but to make that I just think worud cost so much. Citroen couldn't be bothered so I doubt it would work out. I think I'll going to try and coat the exposed bit with a protective paint. I do wonder if the shaft has torsional effects that might cause the coating to crack though.

I think so, the final fitting will take account. These are single lip oil seals and I hope the sleeve works well with them.

Incidentally, do you still have a C5 and has your original work from 2017 lasted?

I'd not worry about that, if you can get any meaningful twist in a solid 20mm rod, even of the bloody awful steel grade Citroen managed to find for these, I'd be quite surprised!

What could go wrong

[aerodynamica]

This week I'll take the parts into the workshops and refine it. I'm concerned that this refurbished rack is not the correct version I.e the pinion might have different teeth to those on the car so I'm not sure I'll do too much to clean up this shaft. I'll work on the shaft that will remove from the car.

This refurbished rack is 3 3/4 turns lock to lock. Although it measures 180mm travel. It makes me think the gearing is different. Unless it's a red herring and that the number of turns is reduced on the car because it's limited by something other that the rack stops? Doesn't seem likely

8x teeth on this pinion is 45° between them so surely the number of teeth on the rack governs it. Need to physically count them.

Other possible red herring is the 2x plastic end stops I found under the rack boots might not be the ones for a short rack. Possibly the shirt rack has an additional pair. Not sure. Kind of thinking out loud here

What could go wrong

Well, you could end up with an LDS puddle, but we are starting at that point, so the only way is up!



Agree with your thinking aloud below, I'm sure it's controlled by the rack rather than the pinion. I think I'd be keen to get this done and fitted, if it becomes possible to "turn the wheels too far" I'd think it was perfectly "liveable" in that state. Repeated the job on the rack / pinion you take off could then be optional / done at your leisure.
